SASH-FASTENER.

To all whom 'it may concern:

Be it 'known that I, GEORGE LEINING, of Roxbury, in the county ofNorfolk and State of Massachusetts, have invented an ImprovedVVindow-Sash Fastening; and I do hereby declare the same to be nllydescribed in the following specication and represented in theaccompanying drawings, of which- Figures 1 and 2 are sections of awindowsash and its frame as provided with my invention. Fig. 3 is afront view ofthe same.

In the drawings, A denotes the windowframe as having .two sashes, B O,arranged within itin the ordinary manner, the lowersash being so appliedto the frame as to be capable of being slid upward or downward therein.

vAn eccentric or cam, D, is arranged on the inner side ofthe frame, andwith respect to the lower sash in manner as shown in the drawings, andsuch eccentric or cam turns freely on a screw, a, which passes throughit and screws into the frame and holds the fastener thereto. On raisingthc sash the eccentric will turn upward on its screw and offer noimpediment to the upward movement ofthe sash; but when an attempt ismade to depress the sash or the sash is left to fall by its own weightor gravitatin g power, the friction of it against the cam will depressthe latter and cause it to arrest the sash.

From the cam a spur or finger, b, projects in manner as shown in thedrawings, its purpose being to prevent the sash from being raised whenat its lowest position, and this the spur or projection will do when itand the cam are so turned on the screw a as to bring the spur or fingeragainst the sash in the manner as shown in Fig. 2.

In order to facilitate the action of the spur or finger the latter maybe provided with a small notch or recess to receive the end of the spur;but if the said end be sharp orpointed -the notch will not be necessary.Furthermore, a projection, c, from the side cf the cam D serves toenable a person to raise the cam out of action with the sash preparatoryto either elevating or depressing such sash.

The invention is also applicable to the upper sash when arranged so asto slide up and down in the frame.

Iclaim- The improved sash-fastener made with the cam and spur, formedand operating as described.
